(54) Pressure welding apparatus and pressure welding method


(57) A pressure welding apparatus includes a pressing die assembly (50) and a comb (70). The pressing die assembly (50) has a plurality of stuffers (54) for pressure-welding electrical wires to the pressure-welding parts (34) of contacts (30). It also has a plurality of pins (60) which are located adjacent to the respective stuffers (54) and which are constantly driven downward by springs so that the pins (60) protrude beyond the lower ends of the stuffers (54). The widths of the respective pins (60) are set so that these widths are substantially equal to the widths of the cavities (16) of the housing (10) in which the contacts (30) are accommodated. As a result, the pins (60) advance into the housing cavities (16) located adjacent to the contact (30) on which pressure-welding is to be performed, and support the housing partition walls (20) from the sides during the pressure welding process.
